THE clarification of aqueous solutions of polyampholytes, as a preliminary to determination of molecular weight by scattered light, is particularly difficult and is in fact the main trouble with ...

Molecular Weight Controls Interactions between Plastic Deformation and Fracture in Cold Spray of Glassy Polymers. Jeeva Muthulingam. ... D 1 and D 2 were calibrated for molecular weights of M n = 40 ...

We report a temperature dependent crystalline structure of spin-coated thin films of high molecular weight regioregular poly(3-hexylthiophene) (P3HT) (Mn ∼ 30000 g/mol) and its correlation with charge ...

At present, several reports are available on APSs, as shown in Table 1. The relative molecular mass distribution of APSs is very wide (5.6 × 10 3 Da–7.6 x 10 6 Da), which is mainly divided into ...

Background and Purpose—Anticoagulation with intravenous unfractionated heparin (IVUH) while awaiting therapeutic oral anticoagulant levels is a common practice in patients with acute and subacute ...
